If the aircraft is the subject of an Irrevocable De-Registration and Export Request Authorisation (“IDERA”) this must be revoked before the aircraft can have the registration mark changed. If the International Interest still remains, a new IDERA quoting the new registration mark should be requested.
If the aircraft is on a permit to fly issued by the Light Aircraft Association please see changes in registration marks on LAA aircraft.
Original versions of the following documents must be returned to the CAA Aircraft Registration Section along with
the completed application. They will be re-issued by the Applications and Approvals department under the new
registration mark. All other documents can be amended by the CAA local area office.
Please note: these documents should be returned whilst the aircraft is grounded and being
changed to the new registration marks. Once the aircraft’s registration has changed its Certificate of Airworthiness (C
of A) is rendered invalid until re-issued under the new marks by the CAA. Also, depending on the C of A category, and
type of flight, the documents mentioned above may be required to be on board the aircraft.
